Tricky question, because you said 'one face'. A face is usually associated with a three-dimensional object, and a side is usually associated with a two-dimensional object.
However, I think I know what you're getting at: It could appear to be a sphere (three dimensional). It is a circle (two dimensional). Keep in mind, that spheres technically have an infinite number of faces (not one), but it's deceiving because you can't see the individual faces of a sphere as they are infinitesimally small and the mind wants to think of it as having only one face since a sphere looks exactly the same no matter what angle you're viewing it from. A circle has one face, of course -- but infinite _sides_. How does that answer your question?

The answer is - a cone.
If you have one flat face and I have one curved face, which one of us is the 3d shape? Anyway, a 3d shape with pne f;at, circular face and one curved face could be: a section of a sphere or a section of an ellipsoid cut by a plane parallel to one of its axes, a section of a paraboloid or a cone. There are probably other shapes.

Get a ball. Draw any closed shape on it. The part inside the curve that you drew is one curved face and that is contained by the surface of the ball which is the other curved face.
